A chemical evidence of reiochemistry in the Diels-Alder reaction of 4- oxygenated quinolinequinones with 1-methoxy-3-trimethylsilyloxy- 1,3- butadienes

The synthesis of four regioisomeric azaanthraquinones (4a, b and 5a, b) was achieved in a regioselective manner by the Diels-Alder reaction of 4- oxygenated 6-bromo- and 7-bromoquinolinequinones (11 and 15) with 1-methoxy- 3-trimethylsilyloxy-1,3-butadien
